Arthritis is a common cause of hip stiffness and pain that gradually affects mobility and quality of life. Doing gentle hip exercises may help restore hip mobility, ease pain, and strengthen the hip.
Hip extension uses some of your biggest, strongest muscles. This movement is involved in many daily activities, such as getting up from a chair, climbing stairs, and walking. It’s also heavily involved in many sports with explosive strength and power.
